Dark screen and can't unlock

A new phone(Samsung A12 ) was purchased 2weeks ago on which the teamviewer host program was installed. First week the program worked without problems. I normally can connect and unlocked the phone(Samsung A12)with remote control from my phone (samsung s10e ). Now I can connect to the phone, but the screen can not be unlocked, it is always dark. I press any buttons the screen does not work to "wake up" as before. In the settings was not any correction. Why did the program stop working remote control( can't unlock)?

When phone is unblocked I can remote him. How to fix this problem( unlocked phone then I am connected with Team viewer)?

    Hello @Klockins,

    I don't think you can completely remove the idle timeout however, you might want to extend it in your settings.

    If it worked before, you should try updating your TeamViewer. Here is the link to download it:

    Please keep us updated, if you solved your problem.

    Hello @Justin,

    I was update my TW, but it doesn't solved my problem. I can remote others phone in my group, but Samsung A12 I still can't "wake up" from black screen.

    Hello, I have the same probleme with a samsung A505FN. Unable to unlock the black screen when screen is locked. I tried to unlock forever the screen but the maximum value possible on the samsung options is 30 minutes.
